Problems solved by technology

[0005] The existing repairing methods using microbial reaction liquid will cause calcium carbonate to penetrate deep into the soil. On the one hand, the calcium carbonate in the upper layer has insufficient bonding density with the soil and has poor erosion resistance. On the other hand, the calcium carbonate in the lower layer will cause soil compaction and affect the plant root growth and nutrient absorption, and a large amount of reaction solution will be wasted, and the cost is higher

Embodiment 1

[0029] see figure 1 , figure 2 , a kind of method utilizing microbial reaction to carry out ecological restoration and soil erosion control, comprises the following steps:

[0030] S1. Loosen the soil on the surface of the soil area to be repaired, and remove weeds;

[0031] S2. Adjust the flatness of the soil area to make the surface smoother;

[0032] S3. Lay a layer of naturally degradable film on the surface of the soil area. After that, evenly dig holes on the film, and dig out the soil in the hole to form a fitting pit, and place a naturally degradable barrier in the fitting pit. 1-5mm passage holes are evenly arranged on the isolation cylinder; the materials of the film and the isolation cylinder are polylactic acid, and the degradation speed is fast. The isolation cylinder can also be made into a cylinder shape by using a film, and one end of the soil body is stretched into the seal.

[0033] S4. Evenly lay a layer of organic clay with a thickness of 2-8cm on the ...

Embodiment 2

[0040] The method of pre-planting ryegrass seedlings on organic matter clay is:

[0041]Sowing seeds (ryegrass seeds) on the cultivation soil layer;

[0042] Lay a layer of plastic mesh on the surface;

[0043] After the seeds are grown, the straw passes through the holes of the plastic mesh, and when the plant grows to a transplantable state, a layer of fine soil is sprinkled on the plastic mesh to cover the gaps in the holes of the plastic mesh;

[0044] Spray the reaction solution once to solidify the fine soil to form a coarse barrier layer, and the roots of the plants are all located under the coarse waterproof layer;

[0045] Transplant (with the soil layer for cultivation and the plastic net board, divided into blocks).

[0046] The effect is that when the reaction solution is sprayed later, under the action of the coarse barrier layer, the downward infiltration speed of calcium carbonate crystals slows down, which is beneficial to the growth of plant roots, and is co...

Abstract

The invention discloses a method for ecological restoration and water and soil loss control by utilizing microbial reaction, and the method of the invention can protect the ecological environment of the slope and prevent the water and soil loss of the slope. It includes the following steps: S1, loosening the soil; S2, leveling; S3, laying a layer of naturally degradable film, digging a chimera pit, placing a naturally degradable isolation cylinder in the chimera pit, and setting a passage hole on the isolation cylinder; S4 1. Spread organic matter clay, pre-plant shallow ryegrass grass seedlings on the organic matter clay, and leave the place corresponding to the isolation cylinder; S5, place the cultivated foxtail grass seedlings in the isolation cylinder; S6, regularly spray The reaction solution of calcium and urea, after the degradation of the film and isolation cylinder, no longer spray the reaction solution, the root system of the plant grows naturally, extending into the soil area that needs to be repaired, so that the organic clay layer and the soil area below are integrated.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a method for carrying out ecological restoration and water and soil loss control by utilizing microbial reactions. Background technique [0002] During the excavation and construction of the expressway, a large number of road slopes will be formed on both sides of the highway, and a large amount of exposed soil will be formed during the mining process, which will cause ecological environment damage, water and soil erosion, and cause economic losses. [0003] In order to repair the slope and control the water and soil loss of the slope, the current engineering usually adopts technologies such as soil transplantation restoration and three-dimensional vegetation net restoration to carry out ecological management on the slope, but the soil transplantation restoration has not been carried out after the vegetation is planted on the bare slope. Maintenance will lead to un...
